GAS-BURNER.

$EEGIFIGA'IION forming part of Letters Patent No. 739,584, dated September 22, 1903. Application filed March 28, 1902. Serial No. lOOAM. (NoinodeL) To aZZ whom it may conccrm,

Be it known that 1E, WORTHY CHANNING BUCKNAM, a citizen of the United States, residing at Geneva, in the county of Ashtabula and State of Ohio, haveinvented a certain new and usefullmprovement in Gas-Burners, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings.

Theobject of this invention is to provide a very efficient gas-burner which while being cheap in construction and very durable shall; properly distribute the gas and shall not backfire-that is, catch fire in the admission-tube. The burner, though advantageous in various installations, is particularly designed for burning vaporized gasolene in an automobile.

My burner consists, primarily, of a continuous coiled pipe perforated on its upper side and on its lower side intercepting a crosspipe, which conveys the gas to the coil. I am aware that it has heretofore been proposed to use a spiral pipe with the gas entering one end thereof; but this is very unsatisfactory in not giving even distribution, there being too much pressure at the end where the gas enters and too little pressure near the opposite end. I know also that it has been proposed to provide a mixing-pipe surmounted by nu-.

merous straightdisconnected cross-pipes. My burner is an improvement over this also not only in its much greater ease of construction and durability, but because, owing. to the dif ferent portions of the burner-pipe being all in continuous longitudinal communication, the gas-pressure in all the different sections becomes equalized and the burner burns evenlythroughout. Thisequalizationofpressure has been found to be very eiiicient in preventing the flame snapping back into the admission-tube. I provide also a very simple means for carrying the burner. This and the particular embodiment of the burner hereinafter described are comprehended within my invention.

The drawings clearly illustrate the invention, Figure 1 being a plan, andFig. 2 a sectional side elevation.

In the drawings, A designates the burnerpipe. This is a continuous coil, being preferably a spiral closed at each end by plugs a. On the upper surface of the burner-pipe are numerous burner-holes a. I

B represents the distributing-pipe,which is a plain tube plugged at its ends by plugs 17 and has its upper surface intercepting the lower surface of the spiral. This is very conveniently accomplished in practice by milling across the spiral a concavity of a radius equal to that of the exterior of the pipe B and milling across the pipe B concavities of a radius equal to the exterior of any portion of the spiral pipe, these latter cavities being curved longitudinally according to their position. Openings are thus producedin the spiral and the distributing-pipe, which aline with each other, as indicated at a in Fig. 1.

The pipes A and B are brazed together with their openings in juxtaposition. Oomnmnication is thus established from the distributing-pipe B directly to each portion of the spiral A. This allows a very efiective distribution, and the different portions of the that the flame may snap back into the admission-tube.

The admission-tube is designated 0. It lies beneath the burner A and communicates with the center of the distributing-pipe B. It is to be'nnderstood that in use a nozzle (not shown.) discharges gas into the tube 0, allowing air to pass around the jet thus formed, as is usual with gasolene-burners.

The burner is carried within a sheet-metal shell D, which surrounds it and rises to any height desired. On the inner side of this shell on opposite sides are riveted vertical cross-plates .D. The projecting ends of the distributing-pipe B occupy central openings in these cross-plates, and the admission-tube C occupies a corresponding opening in the means.

I claim- 1. A gas-burner consisting of a continuous coiled pipe perforated on its upper side and intercepted on its under side by a distributing-pipe communicating therewith at a plurality of points, substantially as described.

2. In a gas-burner, a distributing-pipeconsisting of a tube closed at its ends, an admission tube communicating substantially with the center of the distributing-pipe, and" a spiral burner-tube closed at its ends and crossing the distributing-pipe and communicating with-it on both sides of the center of the spiral, substantially as described.

3. In a gas-burner, in combination, a continuous coiled burner-pipe, a transverse distributing-pipe under said burner-pipe, said burner-pipe communicating with the distributing-pipe at each point of contact between the two, substantially as described.

4:. In a gas-burner, in combination, a distributing-tube consisting of a pipe closed at its ends, an admission-tube communicating therewith, and a burner-pipe above the distributing-tube consisting of a continuous coiled pipe communicating with the distributingtube at numerous points and having burner-openings on its upper side, said coiled pipe being brazed to the distributing-pipe, substantially as described.

5. A gas-burner pipe consisting of a coiled burner, a cross-pipe beneath the burner-pipe and extending beyond it, said two pipes communicating, portions, and a shell surrounding the burner-pipe and having a pair of plates within it through which the ends of the cross-pipe project, substantially as described.

6. A gas-burner consisting of a distributing-pipe closed at its ends, an admission-pipe communicating with the distributing-pipe intermediate of its ends and at an angle thereto, and a burner-pipe above the admission-pipe and distributing-pipe and communicating with said distributing-pipe, said distributingpipe and admission-pipe extending beyond the burner-pipe, combined with a shell surrounding the gas-burner and carrying the same by means of openings through which the ends of the distributing-pipe and the admission -pipe project, substantially as described.

7. In a gas-burner, in combination, a spiral pipe closed at its ends and havingburneropenings on its upper side, a straight distributing-pipe across the under side of the spiral closed at its ends and communicating with the spiral where it crosses the same, an admission-pipe at right angles to the straight pipe communicating with the center thereof, and a shell surrounding and carrying the spiral pipe having an, opening through which the admission-pipe projects, substantially as described.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
